MSP430G2432IPW20R Key Features

• 16-bit core for more computational density and more efficient integer arithmetic than many 8-bit MCUs.
• 16 KB Flash gives more code space for richer firmware while keeping system flash costs lower than larger devices.
• 10-bit ADC enables finer analog measurement than typical 8-bit converters, improving sensor resolution and control accuracy.
• Multiple low-power modes reduce standby current and extend battery life compared with similar higher-clocked parts.
• 20-pin TSSOP minimizes PCB area versus larger packages while still offering up to 16 GPIO lines for real I/O flexibility.
• Industrial temperature rating supports applications that require stability between -40 ??C and +85 ??C.

Typical Applications

• Battery-powered sensor nodes and data loggers that require sub-milliamp standby current and mid-range code memory for communication stacks and data buffering.
• Simple motor or actuator control in industrial automation where a compact 20-pin package and 16-bit timers deliver predictable PWM and capture timing.
• Handheld meters and portable instrumentation needing a 10-bit ADC and low supply current to extend battery run time while maintaining measurement resolution.
• Home and building automation endpoints that use modest code size, multiple GPIOs, and industrial temperature tolerance for reliable field deployment.

MSP430G2432IPW20R Advantages vs Typical Alternatives

The device offers a blend of higher code density and lower active power than many 8-bit MCUs, thanks to its 16-bit architecture and optimized instruction set.

FAQ

What is its core architecture?

The device uses a 16-bit RISC core. This core provides higher integer density and typically fewer instructions per task than many 8-bit MCUs. It helps reduce code size and improves energy efficiency for control and signal tasks.

What voltage range is supported?

Supply voltage ranges from 1.8 V to 3.6 V. This supports common single-cell lithium and coin-cell designs and allows compatibility with typical low-voltage digital interfaces and sensors.

Which package and pin count apply?

It ships in a 20-pin TSSOP package (PW20). The device in the part number with an R suffix is supplied on tape and reel for automated pick-and-place in volume assembly.

Is it suitable for industrial use?

Yes. The part is specified for industrial temperature operation from -40 ??C to +85 ??C. That range supports outdoor, factory, and other fielded equipment that need reliable performance across temperature extremes.

How much analog resolution does it provide?

It provides a 10-bit analog-to-digital converter. That yields 1024 discrete levels, which improves measurement resolution over 8-bit converters and supports finer sensor discrimination in control loops and metering.
